<p>Use the information in this section to troubleshoot common problems.</p>
<p>For issues that you cannot fix yourself … we’re here to help.
If you are an existing Elastic customer with a support contract, please create
a ticket in the
<a href="https://support.elastic.co/customers/s/login/" class="ulink" target="_top">Elastic Support portal</a>.
Or post in the <a href="https://discuss.elastic.co/" class="ulink" target="_top">Elastic forum</a>.</p>
<p>If you encounter problems with your transforms, you can gather more
information from the following files and APIs:</p>
<div class="ulist itemizedlist">
<ul class="itemizedlist">
<li class="listitem">
Lightweight audit messages are stored in <code class="literal">.transform-notifications-read</code>. Search
by your <code class="literal">transform_id</code>.
</li>
<li class="listitem">
The
<a href="get-transform-stats.html" class="ulink" target="_top">get transform statistics API</a>
provides information about the transform status and failures.
</li>
<li class="listitem">
If the transform exists as a task, you can use the
<a href="tasks.html" class="ulink" target="_top">task management API</a> to gather task information. For example:
<code class="literal">GET _tasks?actions=data_frame/transforms*&amp;detailed</code>. Typically, the task exists
when the transform is in a started or failed state.
</li>
<li class="listitem">
The Elasticsearch logs from the node that was running the transform might
also contain useful information. You can identify the node from the notification
messages. Alternatively, if the task still exists, you can get that information
from the get transform statistics API. For more information, see
<a href="logging.html" class="ulink" target="_top">Logging configuration</a>.
